V$ARCHIVED_LOG

This view displays archived log information from the control file, including archive log names. An archive log record is inserted after the online redo log is successfully archived or cleared (name column is NULL if the log was cleared). If the log is archived twice, there will be two archived log records with the same THREAD#, SEQUENCE#, and FIRST_CHANGE#, but with a different name. An archive log record is also inserted when an archive log is restored from a backup set or a copy and whenever a copy of a log is made with the RMAN COPY command.

Column

Datatype

Description

RECID

NUMBER

Archived log record ID

STAMP

NUMBER

Archived log record stamp

NAME

VARCHAR2(513)

Archived log file name. If set to NULL, the log file was cleared before it was archived.

DEST_ID

NUMBER

Original destination from which the archivelog was generated. The value is 0 if the destination identifier is not available.

THREAD#

NUMBER

Redo thread number

SEQUENCE#

NUMBER

Redo log sequence number

RESETLOGS_CHANGE#

NUMBER

Resetlogs change# of the database when this log was written

RESETLOGS_TIME

DATE

Resetlogs time of the database when this log was written

FIRST_CHANGE#

NUMBER

First change# in the archived log

FIRST_TIME

DATE

Timestamp of the first change

NEXT_CHANGE#

NUMBER

First change in the next log

NEXT_TIME

DATE

Timestamp of the next change

BLOCKS

NUMBER

Size of the archived log (in blocks)

BLOCK_SIZE

NUMBER

Redo log block size. This is the logical block size of the archived log, which is the same as the logical block size of the online log from which this archived log was copied. The online log logical block size is a platform-specific value that is not adjustable by the user.

CREATOR

VARCHAR2(7)

Creator of the archivelog:

ARCH - ARCH process

FGRD - Foreground process

RMAN

SRMN - RMAN at standby

LGWR - LGWR process

REGISTRAR

VARCHAR2(7)

Registrar of the entry:

RFS

ARCH - ARCH process

FGRD - Foreground process

RMAN

SRMN - RMAN at standby

LGWR - LGWR process

STANDBY_DEST

VARCHAR2(3)

(YES|NO) Indicates if the entry is an archivelog destination

ARCHIVED

VARCHAR2(3)

Indicates that the online redo log was archived (YES) or that RMAN only inspected the log and created a record for future application of redo logs during recovery.

(YES|NO) Indicates whether or not the archivelog has been applied to its corresponding standby database. YES indicates it has been applied; NO indicates it has not. The value is always NO for local destinations.

This column is meaningful at the physical standby site for the ARCHIVED_LOG entries with REGISTRAR='RFS' (which means this log is shipped from the primary to the standby database). If REGISTRAR='RFS' and APPLIED is NO, then the log has arrived at the standby but has not yet been applied. If REGISTRAR='RFS' and APPLIED is YES, the log has arrived and been applied at the standby database.

You can use this field to identify archivelogs that can be backed up and removed from disk.

DELETED

VARCHAR2(3)

Specifies (YES | NO) whether an RMAN DELETE command has physically deleted the archived log file from disk, as well as logically removing it from the control file of the target database and from the recovery catalog.

STATUS

VARCHAR2(1)

The status of this archived log. Possible values are:

A - Available

D - Deleted

U - Unavailable

X - Expired

COMPLETION_TIME

DATE

Time when the archiving completed

DICTIONARY_BEGIN

VARCHAR2(3)

(YES|NO) Indicates whether or not this log contains the start of a LogMiner dictionary. This column also appears in the RC_ARCHIVED_LOG view.

DICTIONARY_END

VARCHAR2(3)

(YES|NO) Indicates whether or not this log contains the end of a LogMiner dictionary. This column also appears in the RC_ARCHIVED_LOG view.

BACKUP_COUNT

NUMBER

Indicates the number of times this file has been backed up. Values range from 0-15. If the file has been backed up more than 15 times, the value remains 15.

ARCHIVAL_THREAD#

NUMBER

Redo thread number of the instance that performed the archival operation. This column differs from the THREAD# column only when a closed thread is archived by another instance.
